1. Safety
1.3 Important warnings
Important warnings:
Risk of electric shock:
Do not open. To reduce the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer servicing
to quali
fi ed service personnel.
Maximum and minimum ambient temperature:
The maximum ambient temperature for the LED wall is 40 °C, the minimum temperature is -20 °C.
High leakage current:
The combination of multiple tiles in an installation results in increased levels of leakage current. In order to avoid risk of electric
shock due to high leakage current, proper grounding of the installation is required.
Flammable materials:
Keep fl ammable materials away from the installation (such as curtains). A lot of energy is transferred into heat. The installation
should be such that the amount of air fl ow required for safe operation of the equipment is not compromised. Proper ventilation must
be provided.
Disconnect device:
The disconnect device shall simultaneously interrupt all poles of the AC mains supply except for the earthing conductor. It shall be
installed near the equipment and be easily accessible.
Disconnect device:
When the appliance inlets of the individual tiles are not accessible, the socket outlets supplying the rack shall be installed near the
equipment and be easily accessible, or a readily accessible general disconnect device shall be incorporated in the
fi xed wiring.
This equipment MUST be earthed:
In order to protect against risk of electric shock, the installation should be properly grounded. Defeating the purpose of the grounding
type plug will expose you to the risk of electric shock.
Power system:
It is recommended to use a TN-S power distribution system (a power distribution system with a separate neutral and grounding
conductor) in order to avoid large ground current loops due to voltage differences in the neutral conductor. The total electrical
installation should be protected by an appropriately rated disconnect switch, circuit breakers, over voltage protector and Ground Fault
Current Interrupters. The installation shall be done according to the local electrical installation codes. In Europe special attention
should be given to EN 60364, the standard for electrical installation of buildings. In Germany VDE 0100 should be adhered to. In
America, special attention should be given to the National Electrical Code, ANSI/NFPA 70.
